Be it known'that ll, FREDERICK M. FUR- BER, a citizen of the United States, residing at Revere, in the county of Suffolk and State of Massachusetts, have invented certain Tmprovements in Blanking-Machines or l the like, of which the following description in connection with the accom anying drawings is a specification, like re erence characters on the drawings indicating like parts in the several figures. I

This invention relates to machines for use in applying to articles of manufacture fluids such as blacking, sizing or cement, and is herein shown, by way of illustration, as embodied in a machine for blacking the mar gin of the upper surface of the sole of a McKay shoe before the sole is incorporated in the shoe. llt will be readily understood, however, from the following description, that the invention, in its broader aspects, is not limited to machines for performing work of this particular character, and that the constructional details also may be widely varied within the scope of the invention as defined in the claims.

An important object of the invention is to provide means for insuring uniformity in the quantity of fluid applied to the work. The illustrated construction comprises fluid applying means movable to transfer fluid from a supply receptacle to the work, and an important feature of the invention consists in'means for maintaining a substantially constant depth of'fluid in the receptacle in order to insure uniformity in the quantity of fluid transferred.

A further important object of the invention is to avoid, in a machine of the class described, undue agitation of the fluid used by the machine. It is important in the use ofmany kinds of fluid that the fluid be agitated as little as possible prior to its application to the work. It has been found, for example, that in the case of some kinds of blacking such as are used in shoe manufacture, if the blacking is excessively agitated tions of a highly volatile solvent, in order to guard against undue evaporation of the solvent,

In pursuance of the above stated object this invention includes, as a further feature, means for replenishing the supply of fluid to be taken up) by the fluid applying means arranged to e operated only durlng the presentation of work to the machine. The construction shown comprises a blacking receptacle and a b'lacking applying roll arranged to dip within the fluid in the receptacle and to be turned only by contact with the work, and means for supplying blacking to the receptacle arranged (to "be driven through the movement of the roll when the roll is turned by the work.

The above and other features of the invention, including certain details of construction and combinations of parts, will now be described with reference to the accompanying drawings and pointed out in the claims. I

In the drawings:

Figure 1 is a view in front elevation of a machine including structure in which the invention is embodied,

Fig. 2 is an end elevation of the head portion of the machine,

Fig. 3 is a perspective view of a portionbearings for a shaft 10 secured to the front end of which is a work feeding wheel 12. The shaft 6 is provided with fast and loose pulleys, of which only the fast pulley 14 is seen in the drawings, this pulley being arranged to be driven by a belt controlled by a suitable belt shipper indicated at 16. The shaft 10 is driven from the shaft 6 by gearingcomprising a worm 18 0n the shaft 6 and a Worm gear 20 on the shaft 10, the worm and gear being arranged to remain in engagement whatever may be the position of. the wing 8 in its swinging movement its top. The cover 64 is pivote about the shaft 6. The casting 8 is normally maintained in such position as to cause the wheel 12 to engage and feed the work through the provision of a spring 22 that encircles a rod 24 pivoted to a lug 26 on the casting 8, the spring being compressed between a lug 28 on the standard 2 and a collar 30 secured to the rod 24. The rod 24 is connected to a suitable treadle, not shown in the drawings, whereby the casting 8 may be swung in such manner -as to raise the feed Wheel 12 when it' is desired to insert the work for treatment. The normal work feed ing position of the wheel 12 is determined by the engagement of a lug 32 on the casting 8 with the end of a stop 34 which is adjustably threaded in a projection on the head 4. The stop 34 thus determines the limit of swinging movement of the casting 8 under the influence of the spring 22.

Detachably mounted uponabracket 36 on the standard 2 is a casting 38 which is formed to provide a reservoir 40 for the main supply of blacking and a smaller blacking receptacle 42'. The casting 38 slides intoposition on a rod 44 that projects from the side of the bracket 36 and is maintained in position by the engagement. of a spring operated plunger 46 in a socket 48 in the casting, this plunger being under the control of a handle 50. Mounted to turn on the casting 38 is a shaft 52, this shaft being supported for free turning movement on pivots 54 and 56, and secured to the front end of the shaft by means of a nut 58 in such position as to dip within the supply of blacking normally maintained in the receptacle 42 is a blacking applying roll 60. This roll is provided with a band 62 of rubber or similar yielding material for engagement with that portion of the work to which blacking is to be applied, and is positioned in such relation to the feed wheel 12 that the wheel, while advancing the work, maintains the work in engagement with the band 62 under suflicient pressure to cause the roll 60 to be turned by the work and thus to apply to the margin of the work the blacking which adheres to the band 62. A guard 61 of spring metal is attached at its lower end below the roll 60 to the casting 38 and is maintained by meansof a screw 63 with its upper end close to the periphery of the band 62 in order to prevent any unduly large quantity of blacking from being carried 11 ward by the band. A cover 64 is provided or the reservoir 4Q and the receptacle 42, this cover havin an opening to permit the roll 60 to project rom to the casting 38 at 66, and mounted upon the cover is a roll 68 which serves as an edge guide for the work.

In order that the blacking may be. aplied evenly to the work in uniform quantity it is desirable that the blacking in the receptacle42 be maintained at a substantially constant depth. To this end the shaft52 is hollow, as indicated at 70, and is provided with a conduit 72, the open end of which is arranged to dip within the blacking in the reservoir 40, the conduit thus picking up a small quantity of blacking at each revolution of the shaft and transferring it into the hollow interior 70 of the shaft, whence it flows through outlets 74 into a trough 76 leading to the receptacle 42. The supply of blacking in the receptacle42 is thus constantly replenished when the machine is in operation, and through the provision of an overflow outlet 7 8 from the receptacle 42 into the reservoir 40 the depth of the blacking in the receptacle 42 is limited and is maintained constant. The conduit 72 is curved forwardly in the direction of rotation in such manner as to insure that whatever may be the speed of rotation of the shaft 52 centrifugal action will not be such as to prevent the blacking from flowing properly into the interior 70 of the shaft.

In Figs. 1 and 2 a piece of work such as a McKay shoe insole, the margin of which is to be blacked on one side, is indicated fragmentarily at a between the feed wheel 12 and the blacking applying roll 60. The work as thus presented is advanced by the feed wheel 12- and through its engagement with the band 62 on the roll 60 causes the roll to turn. The roll thus applies to the margin of the work on its lower side the blacking which adheres to its periphery as its dips within the supply of blacking in the receptacle 42. As the work advances the operator maintains it with its edge in contact with the guide roll 68, and turns it in the manner required by the contour of its edge.

The shaft 52 turns with the roll 60 during the advance of the work and thus causes the conduit 72 to receive at each revolution a quantity of blacking from the receptacle 40 and transfer it into the hollow interior 70 of the shaft whence it flows through the outlets 74 and the trough 76 into the receptacle 42, replenishing the supply of blacking in the-receptacle. Any surplus blacking is returned through the outlet 78 to the reservoir 40. The depth of the blackin in the receptacle 42 is thus kept practica ly constant, which insures that a uniform quantity shall be taken up by the roll and applied to the work. As each piece of work leaves the machine, the roll 60 and the means for re plenishing the supply of blacking in the receptacle 42 come to a stop, since the feed wheel 12 isprevented by means of the stop 34 from engaging the roll 60. Agitation of the blacking in both the receptacle 42 and the reservoir 40 when no work is in process of treatment is thus avoided.

Although the fluid applying means herein illustrated comprises a roll, it will be readily till lid

uaaaeaa understood from the foregoing description that various means may be employed for transferrin the fluid from the receptacle to the work without affecting the essential. featur'es of. operation of the construction disclosed.
